Query: NC_017267:3612682 Xanthomonas oryzae pv. oryzicola BLS256 chromosome, complete
Lineage: Xanthomonas oryzae; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: These organisms are almost exclusively found associated with their plant hosts and are not found free in the soil. Xanthomonas oryzae contains two pathovars which cause enconomically significant diseases in rice. Xanthomonas oryzae pathovar oryzicola causes bacterial streak. This disease is common in tropical area and can cause crop losses of up to 32%. Xanthomonas oryzae pathovar oryzae causes bacterial leaf blight which is one of the most serious diseases of rice. This disease is common in temperate and tropical areas and can cause significant crop loss.
Subject: NC_001263:243000 Deinococcus radiodurans R1 chromosome 1, complete sequence
Lineage: Deinococcus radiodurans; Deinococcus; Deinococcaceae; Deinococcales; Deinococcus-Thermus; Bacteria
General Information: This red-pigmented organism's name means "strange berry that withstands radiation", marking the fact that this organism is one of the most radiation-resistant known. It can tolerate radiation levels at 1000 times the levels that would kill a human and it was originally isolated in 1956 from a can of meat that had been irradiated with X-rays. The resistance to radiation may reflect its resistance to dessication, which also causes DNA damage. This organism may be of use in cleaning up toxic metals found at nuclear weapons production sites due to the radiation resistance. This bacterium is also a highly efficient transformer, and can readily take up exogenous DNA from the environment, which may also aid DNA repair. This organism carries multiple copies of many DNA repair genes, suggesting a robust system for dealing with DNA damage. The recombination system may rely on multiple copies of various repeat elements found throughout the genome.
